WebAn ARIMA (0, 0, 0) model is a white noise model. An ARIMA (0, 1, 2) model is a Damped Holt's model. An ARIMA (0, 1, 1) model without constant is a basic exponential smoothing model. [9] An ARIMA (0, 2, 2) model is given by — which is equivalent to Holt's linear method with additive errors, or double exponential smoothing. [9] Web16 giu 2024 · SARIMA vs ARIMA forecasts In this exercise, you will see the effect of using a SARIMA model instead of an ARIMA model on your forecasts of seasonal time series.
